A year on from the tragic disappearance of flight MH370 British pilots are calling for more technical aircraft data to be transmitted to a ‘virtual black box’ when a flight gets into problems, so the site and possible cause of a crash can be identified more quickly.

Our immediate thoughts are with the relatives of the passengers and crew on board. It is not clear at this stage what caused the aircraft to lose contact, but there must be a full and thorough investigation to establish the root cause and make every flight safe.
